Squasage

It is thought that the Lorne sausage, which also goes by the names of square sausage, sliced sausage or sausage slice, was an invention of the Scottish comedian Tommy Lorne who lived from 1890 and died in 1935.

It is thought that Lorne sausages were named after Tommy Lorne because of another of his famous catchphrase: "sausages are the boys" - he loved his sausages! He often ate a sausage sandwich between his acts. It has even been suggested that not only were Lorne sausages named after Tommy Lorne and to give people an easy to make sausage sandwich, but that Tommy Lorne was the inventor of the Lorne sausage.

Whoever invented them and whatever they're called a roll and squasage with lashings of sauce is a fine way to start the weekend!
